PEGGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 594,466, dated November30, 1897.

Application filed June 26 1896.

To all whom it may concern:

Be it known that I, ELOUILD DUPLESSIS, of the city of St. Hyacinthe, inthe county of St. Hyacinthe and Province of Quebec, Canada,

5 have invented certain new and useful Improvements in Pegging-Machines;and I do hereby declare that the following is a full, clear, and exactdescription of the same.

My invention relates more particularly to the means for supporting thework during the 'pegging operation, the means for trimming the drivenpegs, and the means for operating the trimmer or cutter; and the objectof the invention is to improve the construction and arrangement of thesemeans, whereby a better-finished and more durable article will beproduced, a great saving of time effected in the pegging of eacharticle, and the liability of the cutter to be damaged reduced to aminimum. w

To these ends the invention may be said, briefly, to consist in mountingupon a vertically-movable slide (the extent of'movement whereof isrestricted by an adjustable yielding resistance of novel construction) aswinging work-support or horn with its axis at an angle to the verticalline of the machine. A rotary cutter, preferablyin the form of a ringsaw-toothed on its inner edge and of peculiar construction, is mountedin the nose of this horn eccentrically to the point at which the pegsare driven and concentrically of-a worksupporting section, whichitencircles, and is driven, preferably, at a high rate of speed, itsoperating-gear embodying a sheave and belt connection in order that saidcutter, in the event of its coming in contact with any obstacle, will bearrested, while the belt can slipover the sheaves and the remainingdrivin g-gear continue to run. The horn or worksupport is also ofpeculiar construction and embodies many features of novelty, for fullcomprehension of which, however, together with the foregoing, referencemust be had to the accompanying drawings, forming a part of thisspecification, in which Figure 1 is side elevation of a pegging machineconstructed according to my invention; Fig. 2, a detail front elevation,partly Serial No. 597,006. (No model.)

As the awl, awl-feed, and driver and their carrying and operating partsform no part of my invention, I will neither illustrate nor describesame, my invention being adapted to any well-known form of awl, feed,and driver.

The pedestal b has a guiding-section 1). formed upon the front thereof,in which a vertical sliding bar 6 is loosely retained. A bracket 5projects above and adjacent to the upper end of such guidingsection anda screw 19 projects downwardly through this bracket.

A forwardly-projectingbracket b is formed uponthe sliding bar 19 andnear the lower end thereof. This bracket is inclined downwardly to theangle at which it is required that the horn or work-support will set andhas an opening therethrough through which set portion 0 are perforatedto take over the 0 standard b while an offset handle 0 is rig-- idlysecured to the front of the horn.

A weighted lever dis fulcrumed to a bracket e secured upon the under'side of the pedestal, and is furnished with a treadle d, and 5 a link fhas its lower end pivotally connected to such lever 01 and its upper endconnected to the slide-bar b near the lower end thereof by means of abolt 1) taking through an opening in the upper end of such link andscrewed into said slide-bar D The horn is caused to hold the workagainst the under side of the head of the machine with a variable degreeof pressure by means of a helical spring (2, carried upon aguidingspindle e, screw-threaded into the bracket b near the outer endthereof, such spring bearing at one end upon a disk I), adapted to slidefreely upon said spindle, but limited in its downward movement by ashoulder b, formed on such spindle, while the other end of such springbears upon a nut taking over the upper screw-threaded end of thespindle. A bracket projection b is formed near the upper end of slidingbar and such bracket has a perforation therethrough which receives thelower end of spindle c.

In order to adjust the normal height of the horn or work-support, thescrew 19 should be adjusted up or down through the bracket b accordingas it may be required to raise or lower the height of such horn. WVhenthe work is in place upon the horn, the pressure of the weight upon thelever d will bear through the horn upon such work, and while such weighthas been found to be just sufficient to hold the work when heavy inplace without injuring it it has also been found to injure light gradesof work. To obviate this difficulty, it will only be necessary to adjustthe spring to offer suflicient resistance to the weight that will allowthe horn to bear upon the work with just sufiicient force to resist theimpacts of the awl and driver without injuring the work.

My improved trimmer consists of a rotary cutter mounted in the nose ofthe horn or work-support 0 preferably as follows: The nose of the hornis recessed to provide a shoulder 0 A bearing-section g is set in thisrecess and formed with shoulders g and g to rest, respectively, upon thetop edge of the nose of the horn and upon shoulder 0 A central aperture9 through this bearing-section receives the spindle of the cutter, andcircular recesses g g are formed concentric with the spindle-aperture gthe inner recess g receiving a downwardly-projecting flange 75, formedupon the under side of a bottom plate of a rotatable cap for the nose ofthe horn. The other recess, 9 (which encircles the one g serves as areceptacle for the rollers or balls 1, upon which the cap 70 bears, thisbearingsection being retained rigidly in place by a set-screw g takenthrough a screw-threaded opening in the horn and adapted to bear uponand pinch the side of said bearing-section g. The spindle for carryingthe cutter has its ends h h diminished and screw-threaded, while thebody portion h thereof is plain and slightly longer than the combineddepth of the bearing-section g and the thickness of the plate 70. Abevelgear 9' is screwed upon the lower diminished screw threaded end hof the spindle and tightly against the shoulder formed by suchdiminished portion,while the cutter is form ed with a central screwthreaded opening through which it is screwed upon the upper diminishedscrew-threaded end 7L2 and tightly against the shoulder formed by suchdiminished end. This cutter is formed of a hubsection m, constituting acentral work-supporting section, and a ring m, having its inner edgeformed with saw-teeth m the upper surface of such saw-toothed ring beinglocated on a line with the upper face of the hub and connected to suchhub by a series of curved arms or braces m secured rigidly to the underside of the ring m and to the lower edge of the hub m.

The rotatable cap has a d ust-guard in the form of a flange k extendingdownwardly from the under side of the plate 70 and adjacent to theupwardly-curved edge 70 thereof and fitting closely about the upper edgeof the bearing-section g, and the upwardlycurved edge being extendedinwardly to closely encircle the cutter and at the same time furnish abearing-surface for the work, sections of the curved portion of theplate 70 being cut away to allow the peg ends to escape from the chamberformed by such turned edge k The required rotary motion is imparted tothe cutter through the bevel-gear r, mounted upon the lower end of thecutterspindle. A bevel-gear r, intermeshing with such gear 9", iscarried rigidly on one end of a rod 1' mounted in bearings inside thehorn, the other end of which rod carries a bevelgear 0' rigidly thereon.A bevel-gear 7*, intermeshing with such gear 0 is carried rigidly uponthe upper end of a rod r galso mounted at its upper end in abearinginside of the horn and having a sheave r secured rigidly thereonnear the lower end thereof, while such lower end projects through andbears in the bottom of the horn. A pair of sheaves 37 37 are mounted inthe lower portion of the horn and adjacent to such sheave 1' and anothersheave r is carried rigidly upon the forward end of the driving-shaft sof the machine, these sheaves being operatively connected together by abelt 0". This drivingshaft is carried in bearings, as usual, near thefoot of the machine and has a tight and a loose pulley s and 8respectively, mounted 011 the rear end thereof, and the tight pulley isconnected by a belt If to a pulley t, mounted rigidly upon thecounter-shaft t that operates the awl and driver, (not shown,) while theloose pulley s is connected to the source of power. The tight pulley shas its face adjacent to the loose pulley made smooth and the loosepulley has a smooth-faced projection .9 on the face thereof that isadjacent to the smooth face of the tight pulley, a grooved extension .9from the hub thereof allowingof a connection between such loose pulleyand a bell-crank lever '0, fulcrumed to a bracket 1;, projecting fromthe rear side of the foot of the machine, while its other arm projectsforward of the machine and is finished in a treadle r Many changes canreadily be made in the precise construction and arrangement of the partswithout departing from the spirit of my invention.
